Usage Guideline
In a large scale BGP network, route reflection is a mechanism used to reduce the needs of fully mesh of
iBGP sessions. With route reflection, an autonomous system can be partitioned into a number of clusters;
each cluster is formed by the route reflector and its client. The connection between clusters is still fully
meshed. However, in a cluster, the reflector needs to maintain connections with all clients, but the client
does not need to maintain connections with other clients. The route reflector is responsible to reflect
routes received from one client to other clients.
Use the bgp client-to-client reflection command on the route reflector to enable reflection of routes
received from the clients to other clients. If the clients are already fully meshed, then use the no bgp
client-to-client reflection command to disable client-to-client reflection because route reflection is not
required.
Example
This example shows how to configure the local router is a route reflector with three neighbors as the
clients. The client to client reflection is enabled to enable the route reflection.
Switch# configure terminal
Switch(config)# router bgp 100
Switch(config-router)#neighbor 10.20.0.1 route-reflector-client
Switch(config-router)#neighbor 10.20.0.2 route-reflector-client
Switch(config-router)#neighbor 10.20.0.3 route-reflector-client
Switch(config-router)# bgp client-to-client reflection
Switch(config-router)#
11-12 bgp cluster-id
This command is used to set the cluster ID in a route reflector cluster. To remove the cluster ID, use the
no form of this command.
bgp cluster-id CLUSTER-ID
no bgp cluster-id
Parameters
CLUSTER-ID
Default
The local router ID of the route reflector is used as the cluster ID when no ID is specified
Command Mode
